After five seasons the ABC fantasy series is finally going to include an LGBT relationship.

‘Once Upon A Time’s’ upcoming fifth season is to feature the show’s first LGBT relationship, creators Adam Horowitz and Edward Kitsis have confirmed. The ABC series comes back to US screens later this month and will see the return of Jamie Chung as Mulan.

Jamie Chung will return to ‘Once Upon A Time’ as Mulan this season.

At a screening of the season premiere on Friday, the showrunners were asked by Entertainment Weekly whether upon Mulan’s return to the series, the show would further explore her feelings for Aurora which had been hinted at back in season three.

“We know that community have been big supporters of the show and we would love to be able to tell a love story that reflects that,” Kitsis answered. “We want the show to reflect the world as it is now,” his writing partner Horowitz added.

“Whether that’s going to be with any particular character, we’re not going to say. It’s something we want to do this year. It’s something we think is due and important to do on the show. This is the world we live in,” Horowitz continued.

Jamie Chung, who was absent from series three is slated to appear in multiple season five episodes in both the first and second halves of the season. Another fan favourite who will also make her return is Meghan Ory as Ruby / Red Riding Hood, who hasn't appeared since season three.

Season five will also see the introduction of many new characters as the land of Camelot is explored, including Princess Merida from Brave, the show’s first Pixar character. Rebecca Mader (Zelena) and Sean Maguire (Robin Hood) have also both been promoted to series regulars.
